Quick answerA roof measurement report does not print a labeled soffit or fascia quantity; it prints eave length and rake length, and you derive fascia LF, soffit area, and gutter LF from those two numbers. Fascia LF equals eave length plus rake length because fascia board runs the entire roof perimeter. Gutter LF equals eave length only, since gutters mount along eaves and not up the rakes. Soffit area equals eave length (plus rake length if the rake is boxed) times the overhang depth, which the report does not measure and you confirm on site or from photos.

Does a roof report list soffit, fascia, and gutter measurements directly?

No. A roof measurement report is built around the roof planes, so what it hands you is a set of edge totals: eave length, rake length, ridge length, hip length, valley length, and total perimeter. Soffit, fascia, and gutter are exterior trim and drainage components, not roof facets, so no report labels a line item "fascia LF" or "soffit SF" for you. You get there by taking the eave and rake totals and applying the formulas below.

This is true across formats. An ESX opened in Xactimate® carries the same eave and rake totals as the sketch data behind it; a PDF prints them as summary rows; an XML for Symbility® carries the equivalent fields. None of the three formats generates a finished fascia or soffit line item on their own.

The formulas: eave and rake totals to fascia LF, soffit area, and gutter LF

Fascia LF = eave length + rake length. Fascia board is continuous around the roof perimeter, so it runs under the eaves and up both rakes on a gable end.

Gutter LF = eave length only. Gutters hang from the fascia at the eave line; they do not typically continue up a rake, valley, or hip, so rake length is excluded from the gutter quantity.

Soffit area = eave length x soffit depth, using the eave length only if the rakes are open (no soffit board at the gable end). If the rake is boxed, meaning it has its own soffit panel, add the rake length to the eave length before multiplying by depth. Soffit depth is a wall-to-fascia dimension, not a roof-plane dimension, so it is never on the roof report; confirm it from a photo or a field measurement, then convert square feet to squares by dividing by 100.

One figure needs a caveat before you use it: rake length as printed on the report is already the actual length along the slope, not the flat horizontal run. It is calculated as horizontal run multiplied by the pitch multiplier (multiplier = sqrt(rise squared + run squared) / run, for example 1.054 at a 4/12 pitch and 1.118 at a 6/12 pitch). Because that multiplier is already baked into the reported rake figure, you use the rake LF as printed for the fascia and soffit math above; do not multiply it again.

Worked example

A single-story gable roof with a boxed rake (soffit runs up the gable end, not just the eave) returns the following totals on the roof report.

MeasurementFormulaResult
Eave length (report)as printed120 LF
Rake length (report)as printed, slope length already applied68 LF
Fascia LFEave LF + Rake LF188 LF
Gutter LFEave LF only120 LF
Soffit depth (field-confirmed, not on report)measured at eave overhang1.5 ft (18 in)
Soffit area(Eave LF + Rake LF, boxed rake) x depth(120 + 68) x 1.5 = 282 SF, 2.82 SQ
DownspoutsGutter LF divided by a 30 to 40 LF field guideline, rounded up120 / 35 = 3.4, round to 4

If the rake in this example were open (no soffit at the gable end), soffit area would use eave length only: 120 x 1.5 = 180 SF, 1.8 SQ. The downspout figure is a starting point, not a code minimum; confirm against the gutter manufacturer's spec and the number of building corners and low points before you finalize the count.

Getting these quantities into Xactimate® or Symbility®

Importing the ESX brings the roof sketch and its eave, rake, ridge, hip, and valley totals into the estimate, but fascia, soffit, and gutter are trim and drainage categories that are added as their own line items using the LF and SF figures you just derived; the import does not generate them for you. The same is true for an XML opened in Symbility®. Menus and import options vary by software version and build, so verify the exact steps in your own install rather than following a fixed click path; Xactware and CoreLogic publish current UI documentation for both platforms.

Once the eave and rake totals are visible in the sketch or the summary rows, note them alongside the trim line items you add so the reviewer can see the source of the fascia and soffit quantities without re-deriving them.

Where the eave and rake totals come from on the report

Sketch My Roof, the site sponsor, prints eave length and rake length totals as part of its residential roof reports, alongside ridge, hip, and valley figures, in ESX, XML, and PDF formats. Order by property address; a Standard ESX is $19, a Complex-roof ESX is $25, PDF-only is $25, and ESX + PDF is $29, with same-calendar-day delivery for orders placed before the 6 PM Eastern cutoff and no subscription required.

You can pull the eave and rake totals straight from the report summary and drop them into the formulas above without re-measuring the roof plan yourself. See Sketch My Roof roof measurement reports for the current order page and format list.

Before you enter the trim and gutter line items

  • Confirm boxed versus open rake from a site or elevation photo

    This decides whether rake length is added into the soffit area or left out of it; the roof report does not state which construction type is present.

  • Confirm soffit depth on site or from a clear photo

    Overhang depth is a wall-to-fascia dimension that never appears on a roof-plane report; it has to come from the field.

  • Check gutter presence per elevation, not just per eave total

    A detached garage, a roof-over-slab addition, or a section with no gutter will overstate gutter LF if you apply the eave total blindly.

  • Look for valley or rake gutters before finalizing gutter LF

    These are uncommon but add linear footage beyond the eave-only default; catching them on inspection avoids an under-scope.

  • Recheck the downspout count against corners and low points, not just the LF guideline

    The 30 to 40 LF rule of thumb is a starting point; actual downspout placement follows roof low points and elevation breaks.

Frequently Asked Questions

Does a roof measurement report give soffit and fascia measurements directly?
No. It gives eave length and rake length. Fascia LF is eave length plus rake length; soffit area is eave length (plus rake length if the rake is boxed) times the overhang depth, which you confirm separately since it is not a roof-plane dimension.
How do I calculate soffit area from a roof report?
Take the eave length from the report, add the rake length only if the rake is boxed, then multiply by the soffit depth measured on site or from a photo. Divide the square-foot result by 100 to convert to squares.
How many linear feet of gutter should I put on the estimate from the eave length?
Use the eave length as printed on the report; gutters run along eaves, not up rakes, valleys, or hips, so those totals are excluded from the gutter quantity.
How many downspouts should I estimate?
There is no fixed count on the report. A common starting point is one downspout per 30 to 40 linear feet of gutter run, rounded up, then adjusted for the number of corners and low points on the actual roof.
Does the rake length count toward fascia or soffit?
It always counts toward fascia LF, since fascia board runs the full perimeter including both rakes. It only counts toward soffit area if the rake is boxed with its own soffit panel; an open rake has fascia but no soffit.
